2.2.2 Removing Racks Before removing the rack, place the lids on the bottles so the
samples do not spill. Remove the bottle rack by lifting the front
edge of the rack slightly to disengage it from the two ramps.
Then, pull it straight out of the refrigerator. Be careful not to
catch the distributor arm against the bottles.
2.2.3 Installing Composite
Bottles
Remove the distributor arm and discharge tube. Remove the dis-
tributor arm stop. If using the two bottle locating base, remove it.
Slide the composite bottle discharge tube on the bulkhead fitting.
Composite bottle kits have two lids, one with a hole drilled in the
center. Screw the lid with the hole in it on the bottle, and place
the bottle in the center of the mounting plate.
Thread the discharge tube through the hole in the lid. Always
use the lid to retain the discharge tube. It prevents the sampler
from spraying liquid inside the sample compartment instead of
the bottle.
2.3 Suction Line The suction line is the tubing from the sampling point to the
pump intake. The 6712FR uses a
3
/ 8 -inch ID suction line of
lengths 3 to 99 feet. Teledyne Isco offers vinyl or PTFE suction
lines. The PTFE tubing has a polyethylene jacket to protect it
from kinks and abrasions.
Secure the base
with these stops.
Install the distributor-shaft extension.
Use the 5
1
/ 4 -inch extension for the 2-bottle
kit. The instructions on page 2-1 show you
how to remove the controller and replace
the extensions for each bottle kit.
Next, replace the controller, and adjust the
distributor arm to position A. Install the
arm and stop. See Installing the Distribu-
tor Arm and Discharge Tube on page 2-2.
Install over the mounting plate at the bot-
tom of the refrigerator, the locating base
which holds the 2
1
/ 2 -gallon glass or 2 gal-
lon polyethylene bottles.
Begin by loosening the ramps. Move them
toward the front of the compartment so
that they will fit under the ridge of the lo-
cating base. (You can also remove them
completely.)
Remove the two front stops, and align the
holes on the sides of the locating base
with the holes for the stops in the mount-
ing plate. Secure the base by replacing
the stops.
Install the bottles, and position the arm
over each bottle.
NEVER MANUALLY ROTATE
THE DISTRIBUTOR ARM.
Ramps located under locating base.
Pull them to the front or remove them.
